MT-CO3 [ENSP00000354982]
Cytochrome c oxidase subunit 3 (Cytochrome c oxidase polypeptide III); Subunits I, II and III form the functional core of the enzyme complex (By similarity)
MT-ATP6 [ENSP00000354632]
ATP synthase subunit a (F-ATPase protein 6); Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the [...]
